Its outstanding feature is the limited space, which is in contradiction with the use conditions of the larger palletizers. Therefore, To a certain extent, the scope of application of the palletizer is limited.

2. There are many dead angles during operation. Most of the existing palletizers use the manipulator to stack the goods. Since the upper part of the manipulator is provided with a lifting structure, the part above the upper limit of the manipulator support arm is the space area that the manipulator cannot reach, that is, the dead angle of operation. The existence of dead space greatly reduces the utilization rate of space, wastes the utilization rate of space, and increases the cost of transportation to a certain extent.
